Great apartment about 4-5 minutes away from the BTS station (Udomsuk). The apartment is light, quite spacious, with a big window and balcony, nice view (facing the city from the 12 floor). Fast wi-fi connection, kitchen, plenty of seats for those who work with laptops, nice couch. It felt very cozy there.
There is also a gym, a steam room and a swimming pool there.
The area is nice - lots of trees (concerning it's Bangkok, not crowded at all).
The big TOPS supermarket, Starbucks and some restaurants are also only 5 minutes away. Generally it's a great place and I'd gladly stay there again.
